Rain tapped the black window while the old clock stopped. Mara Voss entered the library and found the mayor slumped. A silver letter opener stood upright in his gray lapel. The room smelled of rain, old paper, and cedar smoke. Every guest claimed they heard nothing until the clock stopped. Mara knelt beside the body and checked for any pulse. There was none, so she turned toward the silent guests. His right hand was clenched around a torn blue ticket. Mara saw no blood, no struggle, and no forced entry. She unfolded the ticket and read the handwritten name aloud.
